Abstract
Disclosed is a ball coupling for coupling a tractor to a trailer, comprising a coupling ball (14) that is or can be connected to one of the vehicles, i.e. the tractor or the trailer, and a coupling socket (12) which is or can be connected to the other vehicle and can be coupled to the coupling ball (14). More specifically, the coupling ball (14) has a convex contact area (20) while the coupling socket (12) has a concave opposite contact area (22) in a coupling cavity (15). The convex and the concave contact areas (20, 22) rest against each other in the coupled state of the ball coupling, forming a coupling contact area (24). The coupling ball (14) and the coupling socket (12) can be separated between the convex and the concave contact areas (20, 22) when the ball coupling is disconnected. One of the coupling elements, i.e. the coupling socket (12) or the coupling ball (14), supports a seal (18) which seals the coupling contact area (24) against the environment in the coupled state. Furthermore, the seal (18) is accommodated in the coupling element (12) supporting the same so as to be provided with radial play in relation to a coupling axis (A) which contains the center of the coupling ball (14) in the coupled state and traverses the coupling cavity (15) of the coupling socket (12) essentially in the center.
